25 of The Most Iconic Images of Earth Taken From Space

When people and robots launch into space on far-off missions, it's a quiet tradition to briefly turn back toward Earth and take a photo.

These rare views of our home planet - recorded from hundreds, thousands, millions, or even billions of miles away, often with outdated cameras - are rarely as crisp or colorful as the smartphone images we snap today on terra firma.

But the exceptional perspective they afford more than compensates for any visual shortcomings.

Photos of Earth from space not only help scientists understand how a habitable world looks from afar, helping the search to find more cozy planets, but also remind us of a humbling and chilling truth: we live on a tiny, fragile rock that is hopelessly lost in the cosmic void.

Here are 25 of the most arresting images of Earth and the Moon from space that humankind has ever captured. (We recommend viewing this post on a desktop computer.)

A few rare satellites launched by humanity enjoy a full view of Earth from thousands or even a million miles away.

NASA and NOAA created this composite image using photos taken by Suomi NPP, a weather satellite that orbits Earth 14 times a day. You can see the Joalane tropical cyclone in the Indian Ocean (top right).

Their unending gaze helps us monitor the health of our world while catching rare alignments of the Sun, Moon, and Earth.

Orbiting from a million miles (1.6 million km) away, NASA's DSCOVR satellite always views this sunlit half of our planet. This allowed it to take 13 images of the Moon's shadow as it raced across Earth during the total solar eclipse of 2016.

Together, they make up one of the most complete views ever of the event.

But it's when we venture deeper into space that Earth comes into spellbinding focus.

Taken by: Rosetta

Date: 12 November 2009

To rendezvous with comet 67P/Churyumov-Gerasimenko in 2007 - which it will crash into (on 30 September 2016) - the Rosetta spacecraft needed a speed boost with the help of Earth's gravity. This photo it took of Earth shows the South Pole and Antarctica illuminated by the Sun.

The crew of the last crewed lunar mission, Apollo 17, took this 'blue marble' photo of Earth - one of the most-reproduced images in history (though no one is certain which astronaut took it) - from 28,000 miles (45,000 km) away on their trip to the Moon.

Africa is visible at the top left of the image, and Antarctica on the bottom.

About twice per year, the Moon passes between DSCOVR and its prime target - and then we get a rare look at our satellite's far side. This series of images was taken between 3:50pm and 8:45pm EDT. (The yellowish line to the right of the Moon is a camera artifact.)

We know this only because, since the 1950s, nations all around the world have launched people and robots there.

Taken by: Lunar Orbiter 1

Date: 23 August 1966

In 2008, the Lunar Orbiter Image Recovery Project (LOIRP) released this high-resolution version of a Lunar Orbiter 1 photo of Earth from the Moon, which was taken on Aug. 23, 1966.

Lunar Orbiter 1 took this photo while scouting for places astronauts might land on the Moon.

Because 1960s technology couldn't access the full depth of image data that NASA had recorded on analog tapes, however, the Lunar Orbiter Image Recovery Project recently recovered this version of the famous image.

The astronauts Thomas Stafford, John Young, and Eugene Cernan took this video during Apollo 10, the second crewed mission to the Moon - what was essentially a dry run for Apollo 11 (minus the landing).

Because the same side of the Moon always faces our planet, such 'Earthrise' views only happen when a spacecraft is moving.

The Clementine mission was launched on January 25, 1994, as part of a joint NASA-strategic defense initiative. Before spinning wildly out of control on 7 May 1994, it took this composite photo of Earth, as seen across the northern pole of the Moon.

A combination of two photos (one of Earth and one of the Moon) taken by NASA's Mariner 10 spacecraft, which journeyed to Mercury, Venus, and the Moon after launching from a repurposed Intercontinental Ballistic Missile.

On its way to study Jupiter and its Moons, NASA's Galileo spacecraft got its second speed boost from Earth's gravity.

About a week after that maneuver it took this composite image from 3.9 million miles (6.3 million km) away. The Moon, which is about one-third as bright as Earth, is closer to the viewer in the foreground.

Only by traveling hundreds of thousands or millions of miles away, then turning around, can we truly appreciate what the 239,000 miles (385,000 km) between two worlds actually looks like.

Date: 3 July 2003

Nearly 5 million miles from Earth and on its way to the Red Planet, the Mars Express spacecraft pointed back home and snapped this photo. The satellite has orbited Mars and photographed its surface in 3D since December 2003.

This infrared photo, taken from 2.2 million miles (3.5 million km) away, reveals the vast distance between Earth and the Moon - 239,000 miles (385,000 km), or about 30 diameters of Earth stacked together. The Mars Odyssey spacecraft recorded the image on its way to the Red Planet.

Even when paired together, the Earth-Moon system looks insignificant from deep space.

The Earth and the Moon look infinitesimal from 6 million miles (9.6 million km) away in this Juno spacecraft photo, taken on 26 August 2011. Speed-boosting gravity assists are a popular time for adventurous spacecraft to photograph the Earth and its Moon.

NASA's Juno spacecraft took this shot (and many others, which were made into a fantastic animation) during its nearly five-year-long trip to Jupiter, where it is documenting the gas giant in ways scientists had previously only dreamed of.

From the surface of Mars, it could just be another 'moving star' in the night sky that puzzled early astronomers.

Date: 9 March 2004

About 2 months after a textbook landing on Mars, the Spirit rover gazed up at the sky to look for Earth - and found it as a tiny dot. NASA says this "is the first image ever taken of Earth from the surface of a planet beyond the Moon".

In this shot, Earth is roughly 161 million miles (259 million km) away.

Billions of miles from Earth, as Carl Sagan famously quipped, our world is just a "pale blue dot", a small and solitary orb where all of our triumphs and tragedies play out.

Taken by: Voyager 1

Date: 14 February 1990

This photo of Earth - the 'pale blue dot'- is just one frame of a 'solar system portrait' that Voyager 1 took at roughly 4 billion miles (6.4 billion km) away from home.

Here's an abridged text of Sagan's speech about the image:

"We succeeded in taking that picture, and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives.

The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilisations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there – on a mote of dust, suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot.

Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. [...]

To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known."

Sagan's message is immutable: there is only one Earth, and so we must do everything in our power to protect it - and mostly from ourselves.

Japan's Moon-orbiting Selenological and Engineering Explorer (SELENE) spacecraft, also known as Kaguya, took this video of Earth rising above the Moon - sped up 1,000 percent - on the 40th anniversary of NASA's Apollo 8 'Earthrise' photo.
